Well, i’m in my 2nd year….and still havent bought a trailer. 8)
We use my mom’s Town & Country minivan (they actually make great trucks with the rear seats removed!). We only have to take the sidepods and rear wheels off to fit the kart in the van (put a heavy duty moving blanket down first). After a few attempts, we were able to get the packing sequence down pretty well (its like playing Tetris :loony: ). Just make sure you set stuff on top of the kart (if you have to) carefully!. My Dad and i have gotten it down to about only a 30 minute teartown/setup of most of our stuff, which isnt too bad.
…..however, its still a huge pain in the butt. A Subaru is a bit smaller on the inside though, and i’d bet it would be tough. Over time, you’ll accumulate more and more stuff. If you can, get a trailer, i really wish we had one.
